Then, the second scheme (JTAG) is like figure 9-30 ?

Yes, this scheme supports configuration from EPCS, and reprogramming of the EPCS device via JTAG. However, you must take care and read the footnotes - (2) indicates that you need to refer to Table 9–7 on page 9–11 for the MSEL options that can be used with AS mode.

How should I connect MSEL pins? according to table 9-7 all pins to GND is ok?

Grounding all MSEL pins is not a valid Active Serial (AS) mode. Re-read the table, and you'll see several options for AS mode. The mode to select depends on the rest of your board design.
